For a consultation about treatment in Seoul, are you comfortable with the language?

Hi, I'm Emi. I'm planning to go to Seoul next month for a consultation about cosmetic procedures, but I'm a little worried about the language barrier. I can manage basic conversational English, but I'm not confident when it comes to medical explanations...

I've heard there are clinics where they speak Japanese, but what's the reality? Or is it more common to be served in English? Also, is it okay to bring a translation app? (laughs)

If anyone has actually gone for a consultation, I'd love to hear about your experience. Besides language, if there's anything else I should prepare, I'd also like to know. I'd rather go with a clear understanding than feel anxious...
